The Original Energy Attenuator

In true DD fashion of bigger is better comes EA-3.0, the most heavy duty energy attenuator on the market. At 3.0mm of pure butyl rubber, it’s over twice the thickness of most leading brands. This means better attenuation of unwanted energy; road noise, vibration, panel resonances and sound bleed from other cars playing non-DD sound systems. By already being double the thickness of most sound dampers, EA-3.0 negates the need for double layer applications: eliminating double labor.

The EA-3.0 is also the hippest attenuator going, the black aluminum top sheet is adorned with faux brushed aluminum DD logos in red, guaranteeing your install photos will go viral. Corduroy trim is optional in tan and dark green colors, subject to availability.

EA-3.0 comes in bulk packs of 10 sheets with one pack covering 40sq feet. One bulk pack is generally enough to do a single layer application in most standard size cars or more than one layer in sub-standard size cars.

If you’re a competitor in need of extreme energy attenuation, the overall thickness of 0.120” lets you do 2 sheet applications in Sound Organizations where the maximum thickness allowed is 0.250″.

The adhesive used on our EA-3.0 is formulated to be very heat resistant, and it’s also amazingly sticky.  One satisfied user said, “Man, this stuff is really sticky”.
